The 100watt solar panel and the 12volt/20AH/20HR battery was more than ample for my needs while being used at Snowtown.

I could charge three items at the same time if I needed to.

12 volt phone charger for the phoneThe car charger for the laptop also allowed charging via a USB cable so the tablet could have gone there.

This was the first time when camping with the bike that I didn't need to have the bike idle while inflating/deflating my air bed via the bikes 12 volt power sockets.

Usually I would use the laptop in the camp kitchen in the mornings and then charge while at work in the afternoons. Sometimes when not working due to rain I would take a half charged laptop back to the trailer at night and watch a DVD. By the time the movie had finished the battery alone would charge the laptop to full.

What was surprising was that at sunset (trailer lid up) the panel was still charging while I was accessing the trailer though for most of the day the trailer lid was closed.
